<h1 class="banner"><a name="Top"></a>The Search Engine</h1>
<p>A search query consists of one or more specified words. Boolean operators cannot
  be used. Instead of Boolean operators, use the <b>All the words</b>, <b>Any word</b>,
  <b>Exact phrase</b>, or <b>Without the word</b> fields that are provided. The
  search process is not case-sensitive, which means that <font size="3"><tt>Hello, HELLO, and
  hElLo</tt></font> are all considered the
  same. The wildcard symbol <font size="3"><tt>*</tt></font>
  is not supported. When more than one field is used, the query is evaluated with precedence from
  top to bottom. For example, the query:</p>
<div align="center">
<table border="0" width="350" cellspacing="4" cellpadding="4" style="border: 1px solid rgb(128,128,128)" bordercolorlight="#808080" bordercolordark="#808080">
  <tbody valign="top">
    <tr>
      <th width="40%" align="left">All the words:</th>
      <td width="60%">project management</td>
    </tr>
    <tr>
      <th width="40%" align="left"><b>Any word</b>:</th>
      <td width="60%">adopt vision</td>
    </tr>
    <tr>
      <th width="40%" align="left"><b>Exact phrase</b>:</th>
      <td width="60%">Rational Unified Process</td>
    </tr>
    <tr>
      <th width="40%" align="left"><b>Without the words</b>:</th>
      <td width="60%">implementation</td>
    </tr>
  </tbody>
</table>
<br/>
</div>
<p>is evaluated as (project AND management) AND (adopt OR vision) AND (Rational
  Unified Process) NOT (implementation). In other words, the matching pages must
  contain both of the words &quot;project&quot; and &quot;management&quot;, the
  word &quot;adopt&quot; or &quot;vision&quot;, along with the phrase &quot;Rational
  Unified Process&quot;. Matching pages must not contain the word &quot;implementation&quot;. Notice that wildcard searches using the wildcard character <font size="3"><tt>*</tt></font> or boolean operators are not supported</p>
